The Salt of the Earth
13 Ye are the salt of the earth: but if the salt have lost its savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out and trodden under foot of men.
The Light of the World
14 Ye are the light of the world. A city set on a hill cannot be hid. 15 Neither do [men] light a lamp, and put it under the bushel, but on the stand; and it shineth unto all that are in the house. 16 Even so let your light shine before men; that they may see your good works, and glorify your Father who is in heaven.
